To all whom it may concern Be it known that I, CLARENCE E. TYRIOK, acitizen of the United States, residing at Peabody, in the county ofMarion and State of Kansas, have invented new and useful Improvements inLadders, of which the following is a specification.

This invention relates to improvements in ladders and has for an objectthe provision of a step ladder of sectional formation which is capableof being folded into compact form for transportation or storage.

T 0 this end the invention contemplates the provision of a novel form ofhinge for connecting the ladder sections together, the constructionbeing such as to lock the hinge against folding movement until thesections are moved longitudinally with respect to one another and tospace the sections apart after the hinge has been folded to permit ofthe ladder sections being folded over one another.

Other objects and advantages of the invention will appear as thefollowing description is read in connection with the accompanyingdrawings.

In the drawings Figure 1 is a view in side elevation of a step ladderembodying the present invention;

Fig. 2 is a front elevation.

Fig. 3 is a central vertical section.

Fig. 4 is a side elevation of the folded.

Fig. 5 is an end View of the same.

Fig. 6 is an enlarged fragmentary elevation of the hinge which connectsthe ladder sections, showing the position of the hinge ladder when theladder is set up.

Fig.7 is a similar view showing theposition of the hinge when the ladderis folded.

Referring specifically to the drawings wherein like characters ofreference denote corresponding parts, the ladder is made up of twosectional members, the one which is indicated at 10 will be hereinafterreferred to as the rung member, while the other is indicated at 11 andwill be hereinafter referred to as the brace member. These members 10and 11 are hingedly connected at their upper ends and for this purposethe rung member 10 is provided with spaced arms 12, one end of which isrigidly secured to the rung member while their opposite ends arepivotally connected to the brace member as indicated at 13. The rungmem- Specificati on of Letters Patent.

angle iron and bars 14 which are of the plate 17 abuts one of theflanges of the angle iron of which the side bars 14 are fprmed, so thatin order to operate the hinge 1 1s tudinally with respect to oneanother, whereupon the members be moved pivotally and spaced apart asindicated in Fig. 7.

The brace member 11 is also formed of angle iron and includes sectionalside bars 20 which are connected by braces 21 and 22 to lend rigidity tothe brace member. The sections of the brace members are also pivotallyconnected together by hinges 23, which are similar in construction tothe hinges 16 previously described, so that when the adjacent ends ofthe side. bars 20 abut, the sections will be held against relativepivotal movement. 7 7

When the ladder is set up the rung member and brace member may beconnected by hooks 24 to hold the said members in position. When infolded position, hooks 25 serve to hold the sections properly arranged.If desired, one of the sections may have connected to it a. handle 26for conveniently carrying the ladder.

'By reason of the formation of the hinges 16 and 23, the ladder may befolded with the sections folded over one another to provide a compactarrangement illustrated in Figs. 4; and 5.

The invention is susceptible of various changes in its form, proportionsand minor details of construction and the right is herein reserved tomake such changes as properly fall within the scope of the appendedclaims.

Having described the invention what is claimed is r 1.
